Abstract
Various methods for discovering the location of radio frequency (RF) emitters using unmanned aerial vehicles (UAVs) have been the focus of research over the past several years. Our work is aimed at determining the effectiveness of lowaccuracy direction finding (DF) technology to locate RF emissions using multiple UAVs. Small, commercial-off-theshelf (COTS) antenna systems can provide a rough estimate of an emitter's location within a 90 degree or 45 degree sector. Using these DF systems, a team of inexpensive UAVs can be deployed to collect low-accuracy data from multiple positions. A ground station would combine the information. In contrast to typical angle-of-arrival (AOA) methods, this unique technique does not require precise antenna arrays, complex hardware, or significant processing time to locate RF emissions. We present simulation results that show that accurate geolocation of emitters is possible with DF systems using only low accuracy (90-20 degrees) Angle of Arrival (AOA) information.
